Description:
The synformal geometry of the 1.85Ga
Sudbury Igneous Complex (SIC), an impact
melt sheet resulting from largemagnitude
meteorite impact, attests to
post-impact deformation. However, in
contrast to the overlying Onaping Formation,
a heterolithic impact melt breccia,
the SIC shows little evidence for
pervasive ductile strain. This pertains
in particular to its NE-lobe characterized
by a curvature of about 100° in
plain view. This curvature has been interpreted
either as a fold or as a primary
feature. In order to test these scenarios,
a detailed structural analysis was conducted
in the core of the NE-lobe, which
consists of rocks of the Onaping Formation...
